Cultural Conundrums #1

In Istanbul, a huge land reclamation project is nearing completion. A section of the Marmara Sea is being replaced by a park. I crossed a six-lane highway to take a look. After the highway are a pavement and a sliproad and then a café. I walked around the back of the café. There were people sitting, under sunshades, enjoying the view. It comprised a large green area, trees, and beyond that the sea. I was very confused. Why?
